or too near the break in the lens, and hence when the parts areassembled the broken piece 12 and end piece 13 may be loose. If so thefitting of these parts can be made as tight as desired by bending thelugs or fingers l9 inwardly into firm contact with the mounting piecefingers I5, as indicated in Fig. 4. Or the hole for the screw 22 may beslightly too high or too low, in which case the inaccuracy of theposition of the hole can be corrected and the repair assembly tightenedby proper bending adjustment of the fingers l9. Similarly, if the holein the lens is too far from the edge of the lens it can be reamed out toa larger size or elongated horizontally, the fingers 19 being then bentto take up any shake resulting from too great enlargement or elongationof the hole.

Another form of the invention is illustrated in Figs. 6, 7 and 8. Inthis form the repair device 25, Fig. 6, is provided at its ends withapertured arms 21, 28 which for use in making a repair are bent in thesame direction into parallelism with each other as in Fig. '7. Betweenits ends the device is provided with an opening 26. In making a repairthe parts are assembled as illustrated in Fig. 8, with the outer part ofthe mounting or end piece 13 protruding through the slot 26. With thisdevice two holes in the lens are necessary, for the screws 3l, 32, bywhich the pairs of arms 21, 28 are secured separately to the body of thelens. The effect of inaccurate positioning of the holes can beeliminated by suitable bending of the body of the device, between thearms 21, 28. Rocking movement of the device (toward or from theobserver, Fig. 8) is prevented by the firm grip of the arms 21, 28 onthe lens above and below the break, and this in turn prevents likemovement of the mounting piece 13 on the sides of which the sides of theslot 26 bear snugly, these sides being bent toward each other ifnecessary to produce the necessary firm pressure thereof upon the endpiece.

The repair device may be provided with lugs 29, 30 between the opening26 and the arms 21, 28. When bent laterally in the same direction as thearms mentioned the lugs embrace the outer edge of the broken piece l2and thus hold the latter more firmly in place.

It is to be understood that the invention is not limited to the specificconstructions herein illustrated but can be embodied in other formswithout departing from its spirit as defined by the appended claims. Forexample I have shown the repair device as shaped for use with a lenshaving straight side edges but the device can, of course, be shaped foruse with a lens having curved side edges.

I claim:

The combination with a lens and a mounting therefor of the rimlesstype, the lens having a piece broken out at the lens-mounting, thelatter provided with arms embracing and holding the broken-out piece andwith fingers bearing on the outer edge of said piece; of a repair devicebearing upon the said fingers above and below the lens-mounting andhaving pairs of arms embracing the edge of the body of the lens atpoints above and below the broken-out piece and the repair device havingan opening through which the lens-mounting extends outwardly from thebroken-out piece, whereby to hold the lensmounting and the broken-outpiece in their original positions relative to the body of the lens; andmeans displaced from the break to secure the said arms of the repairdevice to the body of the lens.

7. A device adapted for the repair of a broken lens of the rimlessmounting type by restoring and holding in their original positions themounting and a piece broken out of the lens through a hole originallyemployed for fastening the mounting to the unbroken lens, the devicecomprising a member having between its ends an opening enabling thedevice to be passed over the part of the mounting which projectsoutwardly from the broken piece, said member bendable between its endsto provide arms adapted to embrace the broken piece and extend over andpast the same and having means for securement to the lens body at apoint beyond said hole.

8. A device adapted for the repair of a broken lens of the rimlessmounting type by restoring and holding in their original positions themounting and a piece broken out of the lens through a hole originallyemployed for fastening the mounting to the unbroken lens, the devicecomprising a member having between its ends an opening enabling thedevice to be passed over the part of the mounting which projectsoutwardly from the broken piece, and said member having at its endslaterally extending arms bendable to embrace the edge of the lens bodyabove and below the break and having means for securement to the lensbody at points displaced from the break.
